The GenderAid is a novel online decision aid for genital gender affirming surgery. The goal of the GenderAid is to provide a complete overview of the treatment options within the genital gender care trajectory, yet all in one place. The GenderAid has been developed for, and by, the transgender population.For the past 5 years, we have been engaging with members of the transgender community to identify the needs of the population. We then incorporated the feedback as completely as possible into the GenderAid. Here, in addition to supplying reliable and applicable information, safeguarding the interests of the individual is regarded as a priority. The GenderAid can be divided into two websites; treatment options for the feminizing (demasculinizing) genital surgery, or treatment options for masculinizing (defeminizing) genital surgery. Whether you yourself identify as transgender, AFAB, AMAB, non-binary, genderfluid, genderqueer, genderdiverse, still figuring things out, everyone including family or friends, is welcome here!Currently, The GenderAid is available in both English and Dutch. The GenderAid provides information about genital gender surgery, enables you to compare different genital surgery treatment options, and provides custom genital surgery treatment recommendations based on your personal preferences.The GenderAid is NOT affiliated with one specific care center. All medical information adheres to the quality and care requirements of the WPATH, but was collected directly from the community. The researcher team however, is working from the Amsterdam University Medical Centre in the Netherlands. Curious about the research behind the GenderAid?
